This paper investigated the excavated soil stabilized with cement and fly ash in the scarcity of base and sub basematerials. The experimental setup involved adding 6% cement content to the soil and varying percentages of fly ash (0, 5, 10, and 15% by weight). The specimens were cured at room temperature for 7, 14, and 28 days. Several geotechnical tests were conducted on the specimens, including the proctor compaction, compressive strength, indirect tensile strength, and California Bearing Ratio tests. These tests aimed to assess the mechanical properties and suitability of the stabilized soil for pavement applications. The obtained results suggested that the addition of 5% fly ash, along with 6% cement, effectively enhanced the engineering characteristics of the local soil. Finally, the stabilized soil met the requirements specified for the subbase layer, indicating its potential suitability for pavement construction projects.
